    • An illustrative plunger switch may include a movable contact assembly movable with respect to a fixed pair of conductors. The movable contact assembly may include a plunger having a rod fixed to a cage, and a shorting bar moveable with respect to the cage of the plunger but at least partially constrained by the cage of the plunger. The shorting bar may have contact ends that are in line with the internal contact ends of the fixed pair of conductors. The shorting bar may conductively connect the pair of conductors via the contact ends of the shorting bar in only one of an unactuated position or an actuated position of the plunger. A retention spring may be situated in the cage of the plunger for biasing the shorting bar toward the fixed pair of conductors.
    • 示例性的柱塞开关可以包括可相对于固定的一对导体移动的可动触头组件。 可移动接触组件可以包括具有固定到保持架的杆的柱塞和可相对于柱塞的保持架移动但至少部分地被柱塞的保持架限制的短路杆。 短路棒可以具有与固定的一对导体的内部接触端一致的接触端。 短路棒可以通过短路棒的接触端部仅在柱塞的未致动位置或致动位置中的一个中导电地连接一对导体。 保持弹簧可以位于柱塞的保持架中,用于将短路杆朝向固定的一对导体偏压。
